[ 03/77] ALSA: hda - hdmi: Make jacks phantom, if theyre not detectable

From: Greg Kroah-Hartman
Date: Fri Mar 01 2013 - 15:25:13 EST


3.8-stable review patch. If anyone has any objections, please let me know.

------------------

From: David Henningsson <david.henningsson@xxxxxxxxxxxxx>

commit 30efd8debd1ef30be342d374f01e993509f5b76b upstream.

Just as for analog codecs, a jack that isn't suitable for detection
(in this case, NO_PRESENCE was set) should be a phantom Jack
instead of a normal one.

Thanks to Raymond Yau for spotting.
